Re: First attempt to build qt5-qt-webengine on arm64

Hi, I noticed I messed the CC header (alpine...) and exchanged
private mails with Martin. I'm forwarding this to the list in case
someone wants to opine.

I had to patch also third_party/crc32c/BUILD.gn until some check
solution is added to aarch64 in netbsd.

I was thinking of making a package for now with the most common
features in the aarch64 machines supported by netbsd and let
those options so users can build the package matching their machines.

I don't like the idea of pushing ad-hoc runtime detection code in
this package, the amount of patches already here is astonishing
(more than 800). A system function similar to getauxval() would be
more appropriate but that's a good discussion for the netbsd developers,
not for me!

I'll add the code in BUILD.gn and cpu_features.c to support netbsd,
and set arm_cpu_enable_crc32 and arm_cpu_enable_pmull to 0 for now.

Later a netbsd developer can change it for something more suitable.

I'll share with the list if I achieve something, just "make clean;
make configure" is a time destroyer.
